Rossi Long provided structural engineering consultancy services for the large extension to the advanced manufacturing facility at Hethel, near Wymondham in Norfolk. The building comprises a two storey 40,000 sqft extension to the existing facility and provides 16 new starter units for manufacturing firms.

 

Each unit comprises a 11m x 11m x 5m high ground floor manufacturing workshop with a 1st floor office. The new building connects to the existing via a single storey link that including a plant room and WC facilities.

 

The structure comprised a braced steel frame on a typical 11m x 5.5m grid. 11m long, 300mm thick precast concrete hollowcore floor slabs were provided for the first floor structure, specified with a high quality internal finish for the exposed concrete soffit. The roof structure was provided as a steel structural deck. The building is clad in a combination of composite cladding panels and timber cladding. A long span steel brise soleil structure is also provided across the southern elevation of the building. The building is supported on traditional pad foundations and a high specification industrial floor slab has been provided.

 

The building has been designed to incorporate a number of sustainable features including natural ventilation and a biomass boiler using waste generated by the occupants to provide heat and power.

 

RLC value engineered of original design by utilizing long span concrete slabs and significantly reducing the steelwork tonnage. RLC also undertook 3D modeling of  earthworks cut and fill across the site in order to optimize the levels and minimize the volume of material removed from the site.

 

A materials recycling rate of 92% was achieved by reuse of plasterboard, timber, metal and excavated soil.
